Thanks for your persistence, I appreciate it, jt3. See below for some
further developments, if your not to feed up with me yet, haha.


Anyhow, I looked for anything I might have, but all I came up
with was the generic Conexant package, which you have already
seen, and I believe we used the Dell package, anyhow. Probably,
there is not a large difference between the packages, if any.


See my reply to Franc above, tried two different driver revisions,
very similar, same bad results. The problem is with windows, I
think, but I suppose it COULD still be an inappropriate driver
package, but as I said to Franc could be that the original modem
install diskette has something on it that eases the install.


We used a Dell version downloaded from their site. Didn't have anything
that came with the machine, no install disk.
Let me emphasize that IIRC, your symptoms are virtually identical to those
we received. Your mention of the the inf file names jogged my memory--those
were the ones involved--I printed them out at one point.
I did manually clean the registry, but I don't recall if that was actually
necessary in the final phases of our efforts, I think not, since the second
time, a year later, was much simpler.

If you have already uninstalled the enumerator (which appears in
Add/Remove as something like Conexant MDP3880 W {and may even
say modem, but it's the enumerator}) as well as the modem itself
(glee discussed all this, I think) and when you try again, you
*don't* get something like 'PCI HSF Modem Enumerator' installed
first and then the modem itself, but some unknown PCI device,
*or*, in spite of the succession of 2 installation steps in
which you gave it specific file locations for the setup files,
and you still didn't get the modem to operate, you might try the
following.


see reply to Franc. deleted all registry entries related to this
particular modem after again removing it from control
panel-enumerator would not remove from add/remove until I went
through the registry. also removed(renamed) all driver files
installed by previous installs from win/sys/dir and their
corresponding entries in the registry.Now each windows boot gives:
building driver base, insert modem install disk, to which I reply
cancel since I don't have the original disk and am not sure which
of three same modem driver packages to try next. Windows added 3
registry keys on reboot- /services/class/hcfmodem/ empty and
control/asd/root/modem/0000 and enum/root/unknown/0000/mpd3880 pci
modem enumerator


the enum/root/unknown/... key is the result of Win trying to find the setup
(inf) files in the \INF folder, and not succeeding.


These new registry entries are different than what was there
before, so I am hopeful I am not being led up the primose path
again and that if I now give it the driver file directory it is
asking for all will go well, but not holding my breath.



After uninstalling both the enumerator and the modem that had
installed incorrectly, go to the folder into which you extracted
the package. There will probably be four .INF files. You will
need only two of them, and which two depends upon the explicit
model (I can't tell you). One installs the enumerator, and the
other the modem.

These suggestions were based upon the generic Conexant package, which was
the only thing I still had in my backup files, but, though we tried them at
some point, was not the package we used.

As I said, you jogged my memory on the matter.
But if you unzip the Dell package, you should have those infs you mentioned
in a folder you specify, and when the 'found hardware' box comes up, when
you're asked for a disk or location, just cancel it out. IIRC, it may
*still* install something, I don't recall which, logically the modem without
the enumerator, but once the machine is finished booting, you can uninstall
that--but don't reboot. Then, go to that folder where you unzipped the
package. (I'm flying in a fog here with no instruments--it was too long
ago) I don't recall if there is a 'start.exe', or an 'install.exe' routine
in the package that reads the infs and everything, but there might be. If
so, execute that. If not execute the inf (probably the 'bridge' one, but I
don't recall this) using the right-click menu. Again, this is all so hazy
in my memory that I can't promise any accuracy in any of it. One doesn't
know whether to bow to Redmond, Texas, or Mexico, where the Conexant chip is
made.

Once again, best of luck, and hope this helps rather than hinders!
Joe


Find the two infs that have precisely the same modem ID in the
[Strings] section of each file. I.e., in the generic package,
it's CXT\GenericHSF in one set, and CXT\GenericHSFi in the
other. Disable the .INFs that have, say, CXT\GenericHSF by
renaming the extensions to .JSF, and try the installation.

If that doesn't work, try returning the extensions to .INF on
that pair, and changing the extensions on the other pair to
.JSF, and try the installation again.


Ok, but this is dependent on already having those files in either
or both the windows directory and registry-both of which I have
removed. There are two files that seem to be critical mdmp4034.inf
and brdg4034.inf I guess the mdmp4034 is the one for the modem,
but not sure at this point. dell only talks about installing the
brdg4034 file although both files are in the package. This may
have been a case of a corrupted registry as I found numerous
entries for various .inf files for this modem there. One of these
driver packages just says to run setup.exe (which I tried) and the
other from dell says point to the inf file brdg4034 and the directory
it is in and let windows do it's stuff, so I am somewhat confused on
exactly what the right install method should be.

I don't recall if this is something I tried at the time, or not,
but it seems like something I might have tried. Beyond this,
the best I can say is that we had *exactly* the same symptomatic
behaviour you describe, and I did finally get it to work, and it
didn't involve any messing around with the DUN components.


Yeah, it has nothing to do with DUN itself, but with the
interaction between windows and the driver files and the registry.
As with so many win**** screwups it is usually traceable to
screwups with their registry and win**** getting confused and then
going beserk. If I wasn't going to sell this box and if win****
didn't have such a stranglehold over the populace and third party
software developers I would have wiped the drive and installed
another OS. I might just break down and buy a real internal modem for
it, but that might be opening up just another can of worms.



Good Luck,
Joe

I looked through both my steno pads but couldn't find any
notes on the modem installation.

I will e-mail my daughter, since I think she kept the modem
to put on her new XP machine, and she *may* have kept the
notes I wrote up for her at the time, but I wouldn't bet on
it. She only keeps stuff she can leave here with us,
otherwise travels light-- I will look on some of the backup
CDs I wrote at that time, and see what I can find.

Note that glee has given a very good summation of the
problem:

I read his post. Nothing new there, that I did not already know
or try. I appreciate the replies, but really nothing new. Guess
I will have to become a DUN expert to figure out what is going
on. It would be nice if MS provided documentation as to the
highly classified mystical operations of it's OS with regards
to modems, since they have already milked with win98 cow for
what it is worth, but even the one MS tapi "expert" who replied
sarcastically cannot fanthom up an answer,even a sarcastic one.
The problem is with the OS. It cannot properly detect the
installed modem, even with the correct drivers installed. This
is to be expected with MS products, nothing suprising on that
count. I did find out today it has nothing to do with modem
settings as this is a plug an pray modem and the bios does not
have to be disabled for that type of modem.

. Between that
and the links he provided, you'll probably get a clearer
picture than I can provide, but I'll look and see.

Good Luck,
Joe

I am grateful for ANY help.
Several people other than myself have posted on this same
problem and I have not seen ANY definitive answers on it. I
already tried deinstalling under add/remove the enumerator
and then removing the modem and ports, nothing seems to
work. I think this is a registry problem, but there is
nothing in the MS KB about it and they say to remove all
references to the winmodem in the registry, but they do not
tell you where they are, nor how to remove them except for
3com modems that have a special program.

Sorry about the vagueness, but as I said, it's been a
while.

As well as I can recall, which is not very well, you end
up with two different things installed if you try the
directions/std install. I tried many different
permutations of install, and could easily be mixing them
up now. Uninstalling the modem doesn't uninstall the
enumerator, I believe; you must uninstall that explicitly
in Add/Remove. I believe that it was important to get all
of the stuff uninstalled to get it right finally.

I have an old notebook I used at the time and may have
some notes on it--will see if I can find it and get back.
That is, if you want it. I'm no professional, and don't
claim to know what I'm doing. It's mostly empirical, just
as for virtually everyone else here, and if you can't
handle that, then I'll be of no use to you.

Thanks, not sure I know (or you do) what you mean.

If I install the latest driver package that IS the
enumerator, it automatically installs the modem on the
OS. So, how can you install the enumerator without
installing the modem?? In fact, I did install the
enumbetor/driver package prior to letting windows try
it's install as I recall.

Also nobody has said anything about what exactly the bios
settings should be on this install. Some say to disable
the irqs for the modem; which I'm guessing is "reserved"
under my bios. I think I may have tried it both ways. The
problem appears to be a windows screw up in the registry
and windows is confused again. There have been numerous
posts on this problem from different individuals (google
it) and no one has explained how this install process
works, what the interaction with tapi is and what to do
about it.

Also does anyone know what the effect of removing
unimdm.tsk from the control panel will do on this system?
Is it possible to reinstall it without reinstalling the
whole OS if I try removing it?

Maybe MS wants me to call in any pay for tech support so
they don't give the real answers to this problem :-(.

I hesitate to say much when it's so fuzzy in my
memory--these days 2 years blanks me out pretty
badly--but my daughter's Dell had the same problem
(same modem) and as I recall after thrashing with it
for the better part of a month, I finally decided that
the problem seems to occur as a result of the modem
being detected and an install attempted before the
Conexant enumerator is installed.

When they get installed in the wrong order, it does
just what you described.

I *think* I uninstalled the mess and tried again (one
of many retries), not allowing the modem to install
initially, and then when the enumerator gets installed
(I forget what it's called--HCF Modem or some such) you
can let it install the modem.

It worked well enough that when I had to reinstall it
the next year she was back from college, that I was
able to do it with only a little fumbling around. She
isn't here, and no longer has the machine anyway, or
I'd check it out.

Hope this is of some use.

cannot get dun to work with aztech mdp3880-w(u) modem.

installed latest drivers, install went fine. "more
info" reported info from the modem.

When I try to dialout using dun i get : "error 633-
modem is not installed or configured for dialup,
double click on the modems icon in control panel"

When I do the above, it tries to reinstall the modem
drivers,even though they have already been installed.

Tried on of MS's solutions and rebuilt telephon.ini,
still no go. Also did their registry fix for
telephon.ini

tried uninstalling and reinstalling drivers and modem
still no problem. Modem now assigned to com3 IRQ 10

in my Dell dimension bios, there is a section for all
the irqs where u set it to either available or
reserved, but I was told that this is only for
non-plug and pray modems and I got a message from
windows saying this is plug and pray modem. IRQ is
currently marked available in bios.
